Specification of Letters Patent.

Patented Feb. 5, 1907.

l To LM wlwm, 'it may concern:

and have met'with more or less success. The old-fashion buckle having a bow and pivotedl tongues has been most generally used; but there is a decided preference for a buckle having no movable parts, and this present invention is of this last-mentioned character.

' The invention consists ofa rigid one-piece buckle, preferably struck up out of sheetsteel, having flanged sides, concave-convex end bars, and oppositely-deflected flat crossbars, one of the end bars havin several fixed and rearwardly-projecting teet i, an intermediate tooth being longer than the'others, so as to insure positive engagement with the strap, the crossar next to the teeth being elevated 0r deflected toward the front of the buckle, so as to bend the strap sufficiently to insure the engagement of the teeth with the strap, and the other cross-bar being depressed or deiected rearwardly, so as to 'compensate for the thicknesses of the strap sewed to it and the other strap which is passed over it, the end bars being curved so as to bite the strap, and thus prevent its accidental slipping, and the sides being elevated to form a sort of trough within which the .straps are held against lateral displacement, adjustment be-' ing effected by disengalging the strap from engthwise in the desired directionfto `len then or shorten the an'd again engaging the strapwith the teeth to'ii'x the adjustment;`

In the accompanying drawings, illustrating the invention, 1n the Aseveral figures of which ,like parts are similarly designated,

Figure 1 isa plan View of the buckle and strap members. Fi 2 is a longitudinal sec-- tion of the parts o Fig. 1 Fig. 3 is aplan view of the b uckle detached. Fig. 4 is a longitudinal section of the buckle detached.

All of the views are on a large scale.

The sides l are of a height above the back base-line sufiicient to constitute flanges, said sides standing upat right angles to the end bars and cross-bars. The end bars 2 and 3, connecting the sides, are convex on the face and concave on the back, so as to insure strength and present, respectively, a pleasing finish and strap-engaging edges. The end bar 2 has the rearwardly-projecting teeth 4 and 5, the intermediate tooth 5 being longer than the others to insure positive engagement with the strap as the latter is impaled-,u'pon the teeth. The cross-bar 6 next t0 the toothed end bar is deflected forwardly pr elevated, and the cross-bar 7 is deflected rearwardly or depressed. These cross-bars are flat, so as Ato reduce thickness orbulk of buckle and straps when applied. Between the several bars-are the slots or openings 8, 9, and 10.

f In using the buckle one end of a strap 11 is passed under end bar 3, then through slot 10, and over cross-bar T, nud then rearwardly through slot 9 aud heul bueh upon itself and sewed or fastened du u uuou ilsell to secure the buckle 1n place. The ullul' strap 12 1s .passed under cud luu 2, then forwardly through slot b. nud engaged u il h the teeth 4 andv 5, and then hun( over cross-bar 6 and over thelooped end ol strap I l, and then under the end bar 3. These straps are confined thus in adjusted position and are held against lateral displacement by the side flanges 1. When further adjustment is required, the strap 12 is drawn out sufiiciently to free it from the teeth, and then moved longitudinally to a new adjustment, and

again pulled into engagement with the teeth.

When 1n engagement with the teeth, the strap is held from working loose by its being bent over the elevated cross-bar 6 and under the end bar 3.

Thus a very inconspicuous, simple, and

easily-adjustable buckle isprovided and one which may be made in one piecefrom sheet metal. -I/Vhen in use, only the end bars appear with any prominence, and the sides are so thin as not to attract notice.

`The buckle is especially adapted, for the` ico' side straps' of trou'ers-and may also be used on kneepantg vfor gertersl, Suspenders, neck-y Weer, vests, baekstrapsof trousers,'a.nd uponl other articles.
